项目摘要

The root zone of cell seedlings were limited capacity of cell. Therefore The transplant proper time is shorten, it is easy to elongate, and aging. There is a fault that it is not easy to apply with big crops of crops and the seedling with a bad germination rate. The cell sheet method of raising seedlings of the no medium designed in this laboratory is handy and light weight.Because moisture and liquid manure are always supplied in the cell sheet method, the faults of the above-mentioned cell seedling is canceled. Especially, the weight when transported, becomes about 1/2-1/3 of the cell trays. Moreover, taking root and the early growth of the drying condition in summer were extremely better, and higher than usual cell seedlings also that amount, even cell sheet seedlings had no medium and were imaged it was difficult that transplanting to the outdoors field This cell sheet : in putting to practical use. (1) It is not easy to break after it is necessary to put by one hole and seedlings … More transplants though the cotton cloth and the pdyester unwoven cloth, etc. were used as upper protection to protect the rhizosphere. (2) Th peeling off of seedlings is easy in transportation. (3) It was necessary to supply phosphorus dividing to control algae of the rhizosphere and the generation of mold in the cell seedling, therefore usual hydroponics media could not used.Surface of the cell sheet coated by a dry peat-moss, and the generation of algae and the mold of the rhizosphere was able to be controlled, and the problem of (1) and (3) was solved if surface of the cell sheet were shaded. (2) was solved by putting the size of the box and the cell sheet together from the cell tray more strictly when transported, and because changing the material of the sheet from 'Love Mat U' to 'Tetoron No200', root pasting with the sheet were improved. A suitable thing was not able to be found though the result of the above-mentioned was receivedr, cheap materials with equal to 'Tetoron No200' a performance were retrieved. However, materials have almost understood the influence is not exerted from the process in the growth of the plant. In the experiment in the Kyoto University Kyoto farm, cell sheet seedlings. The seedlings promoted in Kyoto University were sent to various places and grew under various field. Under hydroponics and bench, cell sheet seedlings grew better than cell tray sheedrings. Under other field, cell sheet seedlings grew little less than cell tray sheedrings. It seemed that the cell sheet had the possibility of practical use enough above. Less

细胞幼苗根区细胞容量有限。因此移栽所需时间短，易延长，易老化。有一个缺点，就是作物产量大，发芽率低的苗木不好用。本实验室设计的无基质细胞膜法育苗，操作简便、重量轻，由于细胞膜法总是提供水分和液体肥料，消除了上述细胞育苗的缺点。特别是，当运输时，重量约为电池托盘的1/2-1/3。而且，夏季生根和早期生长的干燥条件极好，细胞苗的数量也比平时高，即使细胞片幼苗没有培养基，也很难将这种细胞片移植到户外：在实际使用中。(1)…需一穴插苗后不易破损更多的移栽通过棉布和涤纶无纺布等作为上层保护，以保护根际。(2)Th在运输过程中容易剥离。(3)为了控制根际藻类的生长和根际霉菌的产生，需补充磷，因此不能使用常规的水培基质，细胞膜表面涂有干泥炭苔藓，可以控制藻类的生成和根际霉菌的产生，如果对细胞膜表面进行遮荫，可以解决(1)和(3)的问题。(2)通过在运输时将盒子和细胞片的尺寸从细胞托盘更严格地放在一起来解决，并且由于将片材的材料从‘Love Mat U’改为‘Tetoron No200’，改进了与片材的根部粘贴。虽然收到了上述结果，但没有找到合适的东西，检索到了相当于‘Tetoron No200’a性能的廉价材料。然而，材料几乎已经理解了这种影响不是从植物生长的过程中施加的。在京都大学京都农场的实验中，细胞膜苗。在京都大学推广的苗木被送到各地，在不同的田野下生长。在水培和梯田条件下，细胞膜苗的生长情况好于细胞盘膜。在其他条件下，细胞膜苗的生长略低于细胞盘膜。看来，单元板具有足够的实际应用以上的可能性。较少
